2. New calculating normal vectors proc that use some data produced

3. On http://board.flatassembler.net occasionaly there are some disccusions

about optimizing. Some clever people, wich skills and competence I trust,

claims - for CPU's manufactured last ~15 years size of code is crucial
|
||||
for speed. (Better utilize CPU cache).
|
||||
So I wrote some 'movsd' mnemonics instead 'mov [edi],sth'; 'loop' instead
|
||||
'dec ecx,jnz sth'. Moreover I come back to init some local varibles
|

by 'push' (flat_cat.inc). I took effort to change divisions to

multiplications two_tex.inc (works ok in fpu only Ext = NON mode and

of course in Ext = SSE3 mode), grd_tex.inc (single line not parallel

muls, whole drawing routine 4 divs instead 27 divisions),
